A neonatal patient exhibits a heart murmur upon auscultation one hour after birth. The respiratory therapist is having difficulty maintaining adequate oxygenation saturation in spite of increasing FIO2. Which of the following should the respiratory therapist recommend?
A. transillumination
B. cardiac angioplasty
C. diagnostic chest percussion
D. echocardiography
Answer: D. Although it is common for a neonate to exhibit a cardiac murmur right after birth, when considered in connection with other signs, such as poor oxygenation in spite of increasing oxygen delivery, the respiratory therapist should suspect congenital cardiac abnormalities. The best way to broadly assess for this kind of congenital issue is to perform echocardiography.
